I Think The answer is a I hope it helps My friend Message Me if I’m wrong and I’ll change My answer and fix it for you
Answer:The answer is because of the gravity and the mass formed in the sun, the magnetic field reacts to it and leaves a fault on earth. wind goes by the earth and procides to be ok
Explanation:that is it
Answer:
the electric charge in the Earth is -5.91 × 10⁵ C
Explanation:
Given the data in the question;
Electric field E = 131 N/C
we know that; radius of the earth r = 6,371 km = 6371000 m
and Coulomb's constant k = 8.99 × 10⁹ Nm²/c²
Now, using the following formula to calculate the charge;
E = k × Q/r²
we make Q the subject of the formula
Q = Er² / k
so we substitute
Q = [ 131 N/C × ( 6371000 m )² ] / 8.99 × 10⁹ Nm²/c²
Q = [ 5.317242971 × 10¹⁵ ] / [ 8.99 × 10⁹ ]
Q = 5.91 × 10⁵ C
Since the electric field pointing downward
Q = -5.91 × 10⁵ C
Therefore, the electric charge in the Earth is -5.91 × 10⁵ C
Answer:
(2) the work required to move the electron is 4.8 x 10⁻¹⁹ J.
Explanation:
Given;
potential difference, V = 3.00 volts
charge of electron, q = 1.6 x 10⁻¹⁹ C
The work required to move an electron is calculated as;
W = Vq
where;
W is the work done in Joules
Substitute the given values and solve for W;
W = (3.00)(1.6 x 10⁻¹⁹)
W = 4.8 x 10⁻¹⁹ J.
Therefore, the work required to move the electron is 4.8 x 10⁻¹⁹ J.
Answer:
The frictional force points up the incline.
Explanation:
It is given that, the crate is at rest on the incline. We know that the forces acting on the crate are force of gravity, normal and the force of friction. We know that the frictional force is the force that opposes the motion of an object.
In this case the crate is at rest. The crate will have static friction, that points up the incline.
So, the correct option is (A) "the frictional force points up the incline".
